Airblown Inflatable fixer
I use this product to help fix older inflatable decorations with porus fabric. It works like a charm! I use a old paintbrush and evenly distribute the paste all over the fabric. The liquid is very thick so you need to be patient but at the end of the day it is totally worth it. Using this product saved three old christmas inflatables of mine. It is overall an awesome product that I highly recomend using.

    I returned this product for the paste based on the recommendation of a carpenter. I used the FlexSeal Paste to seal around a window air conditioner. It did okay. Can any product advertised so heavily really meet or exceed expectations?

    Hoped for better results
    [This review was collected as part of a promotion.] I currently have an older concrete stationary/utility tub where my washing machine empties into. It is leaking underneath so I was hoping that using the Flex Seal Liquid would help me to seal off those leaks. The can opens easily just as a paint can & after stirring I applied with a brush. It did have a smell to it but it wasn't anything that was so strong that it was overpowering. The Flex Seal seemed to apply fairly easily. Unfortunately, when I went to test it out, my tub was still leaking just as badly as before. I'm hoping that maybe it's because I just need to apply a thicker/2nd coat so I will be giving that a try. It was a bit difficult to apply due to being on the underside of the tub. I also am not 100% sure that the concrete was dry. It looked dry on the surface but not sure if there might have been moisture within the concrete that impeded the ability of the product to work as intended. While I was disappointed with the result, I am not writing it off completely. I'm going to give it another shot & hope that with an additional coat, I will see the results I was hoping for.

      Nice
      [This review was collected as part of a promotion.] I received this can of flex seal in white, been waiting to try it on my gutters cause I have a couple leaks. As soon as I get my gutters clean I will give the flex seal a shot. All the reviews I have read have been pretty good. Thanks flex seal for the opportunity to try out your product.

        Works wonders
        [This review was collected as part of a promotion.] I got this Flex Seal it’s liquid rubber in a can! I used it on my gutters and it’s very easy to use! You can brush it on, roll, dip or even pour it on, it can be used on anywhere you need a watertight, flexible coating. Prevents rust and corrosion and it’s even mildew and chemical resistant. It’s non toxic, non hazardous and non flammable, it’s even safe around pets and plants.

          Great Sealend!
          [This review was collected as part of a promotion.] I got the FLEX SEAL LIQUID in gray because i got a leak in my Sunroom Roof. The roof is out of Metal and it apears that the leak was right at the seal. I brushed some Flex Seal on the area, a couple days later, it rained and i did not have a leak anymore. I am so impressed with the Flex seal how great it works and how easy it is to use and highly recommend it !
